Use multithreaded loading of EXR files which is enabling by call of
setGlobalThreadCount function from OpenEXR library to set up number
of used threads to number of system threads which speeds up loading
high-resolution files on multi-core / multi-cpu systems and allows
to work with high-resolution sequences in clip editor and sequencer.
The main reason to have this is so renders can be scripted to write to a specific file without having to do annoying tricks like set a dummy start/end frame range, render an animation and work out the current frame image will be written to, then rename after rendering.
Also made some 'char *' args into 'const char *'
- removed deprecated bitmap arg from IMB_allocImBuf (plugins will need updating).
- mostly tagged UNUSED() since some of these functions look like they may need to have the arguments used later.
- Saving a typical byte buffer as an exr wasnt converting into linear colorspace.
- Remove checks for 1 and 2 channel images, these will write as RGB anyway and are very rare.
- 3 Channel images were having the alpha channel written from the red color channel, write 1.0 instead.
looks like a threading problem:
Easy to redo, 1024x436, FSA, 4 threads.
With 1 thread it runs ok, need to look into this further but no time now so reverting.
famous upside down EXR bugfix from Xavier Thomas
- Files from blender 2.4x will be flipped on load.
- New files will be saved correctly

tile cache code in imbuf, but it is not hooked up to the render engine.
Imbuf module: some small refactoring and removing a lot of unused or old code
(about 6.5k lines).
* Added a ImFileType struct with callbacks to make adding an file format type,
or making changes to the API easier.
* Move imbuf init/exit code into IMB_init()/IMB_exit() functions.
* Increased mipmap levels from 10 to 20, you run into this limit already with
a 2k image.
* Removed hamx, amiga, anim5 format support.
* Removed colormap saving, only simple colormap code now for reading tga.
* Removed gen_dynlibtiff.py, editing this is almost as much work as just
editing the code directly.
* Functions removed that were only used for sequencer plugin API:
IMB_anim_nextpic, IMB_clever_double, IMB_antialias, IMB_gamwarp,
IMB_scalefieldImBuf, IMB_scalefastfieldImBuf, IMB_onethird, IMB_halflace,
IMB_dit0, IMB_dit2, IMB_cspace
* Write metadata info into OpenEXR images. Can be viewed with the command
line utility 'exrheader'
For the image tile cache code, see this page:
http://wiki.blender.org/index.php/Dev:2.5/Source/Imaging/ImageTileCache
Now it's a bit more robust, tagging images with profiles when they're loaded,
which then get interpreted later on by conversion functions. Just Linear RGB
and sRGB profiles at the moment, same as before.
This commit fixes Martin's problem with EXRs and Multilayer images loading/
saving too dark, and it also makes the sequence editor work correctly with it too.
Also fixes:
[#19647] gamma correction with color management is reset when resetting Curve
[#19454] 2.5: Dither does not work when Color management is enabled
svn merge https://svn.blender.org/svnroot/bf-blender/trunk/blender -r19820:HEAD
Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.
Small one: changed the string attribute in multilayer exr files to be:
"2.43 and newer"
To indicate that it's about compatibility of the exr file, not the version
Blender saved it in.
For simple RGB(A) files, the channel names in openexr were supposed
to be simply "R" "G" "B" and "A" too.
Other programs like other names... like lower case, or like "ambient.r"
Tested with file from renderman.
Press Rkey in compositor for reading back render results and invoke a compo.
This now correctly reads AO (skipped it sometimes) and it makes a correct
composite.
FSA todo:
- hotkey + button for reading all samples back + composite
- solve black border around image
* fix [ #6105 ] Blender crashes when opening multilayer with node in compositor
- Mem_IStream membuf was allocated on the stack, so it caused major troubles when
out of the function scope. Now allocate it on the heap and let OpenEXR deal with
freeing it.
- moved + added delete file;'s for completeness
- fix for 3DPlugin compile
- cleanup of bullet path
- removed PHY_ODE project from 3D plugin too, not used anymore
Now all configurations should build again, let me know of any problems!
Not been able to test if the 3DPlugin is actually working,is job for another day ;)
Also the 3DPlugin is compiled without OpenExr, this needs to be looked into once too.
